Type description
Take 350QZB-50 as an example
350: the nominal diameter of the pump
Q: submersible
Z: axial flow
B: semi-adjustable blade
50: 1/10 of the pump specific speed (take the integer part)
According to different pump specific speeds, the flow capacity range of this type of axial flow pump can reach up to 700m3-1400 m3
The principle of Axial flow pump is to lifting water according to the thrust caused by the impeller when rotating. Because water moves along the axial in the impeller, so we called it axial flow pump.
In accordance with its mode of installation, axial flow pump can be distinguished into three class: vertical, horizontal, inclined. Their structures are almost the same. Now the vertical form is used widely. The main accessories contains bell-mouthed pipe, impeller, guide blade, outlet syphon, shaft and bearing, stuffing box, etc.
Summarize of QZ series Axial flow pump:
Installation of water flow Channel: in terms of recommended sample installation diagram
The form of water exit: flap valve or other ways
Installation ways: suspended by bent pipe; suspended in well casing, etc.
Motor
Submersible motor
Power Level: electrical performance conforms to GB756
Protection level: IP68
Cooling method: ICW08A41
Basic installation form: IM3013
Voltage grade: ≤355kw, voltage,380v/660v; 355kw,voltage, 380v, 660v, 6000v, 10000v
Insulation level: F
Rated frequency: 50Hz
Length of cable: 10m
Shaft seal
There are two or three stages of mechanical seal. The first stage called carborundum (directly contact with water). The second and third stage called graphite and carborundum.
Leak proof Equipment
QZ, QH series pump have been equipped with leak proof sensors. When the oil tank, the inner part of motor or the junction box has been leaked by water, the sensor will signal or made the motor shut down, and retain the malfunction signal.
Over heating protection system
A overheating protection device is fastened on the motor winding. When the temperature exceeds the stated ＆#118alue, the device will signal or made the motor shut down.
Rotation direction:
Seen from the top of the motor, the impeller is rotating clock wisely.
Application
QZ series axial flow pump, QH series mixed-flow pump is widely used in industry and agriculture water lifting, urban water supply, light polluted water discharge and other water transfer project.
Working condition
Clean water with the temperature no more than 50 or some liquids that are similar to water.
- Q:When the pump is running with frequency conversion, the instantaneous power is greater than the power frequency operation, and the actual flow and lift are less than the power frequency. When running, the efficiency is very low. Why?
- There is a running curve for the fan and water pump.Enough is enough
- Q:hiI have very low pressure only on the hot water in my kitchen sink. Cold water is fine. Can anyone recommend a water pump/power shower i can use for boosting my hot water in the kitchen sink tap?Ive already tested the faucet by swapping the water supplies.thanks
- Why do you need high pressure from the hot tap?
- Q:I have had this water pump changed 2 times in 5 years is this normal for this car? It has a v6 motor.
- i wouldn't think that was normal, but what do i know? point being.....yea water pumps, in my experience, are pretty difficultly to change out....no average Joe could do it.
- Q:All water pump have diferent caracteristics, but it is imposible to overcome a certain hight...what is that hight and why?
- More height requires more push (pressure) to achieve it, but over time you will get to a point that the flow is no longer laminar but turbulent and then the motion is very chaotic and very little makes it to the other end, most is lost in friction
- Q:Could someone tell me the procedure for removing & installing a water pump on 97 buick skylark 3.1L 3100 SFI?
- Water Pump Removal Disconnect negative battery cable. Drain cooling system. Remove air cleaner (if necessary). Loosen water pump pulley bolts. Remove serpentine drive belt. Remove water pump pulley bolts and pulley. Note position of locate tab on top of water pump for installation reference. Remove bolts, water pump and gasket. Installation Apply thread sealant to water pump bolts. To complete installation, reverse removal procedure. Fill and bleed cooling system (fill reservoir and radiator, run engine until upper rad hose starts to become hot. Top off and replace cap) Torque Specs Water pump bolt................89 Inch Pounds Water pump pulley bolt .....18 Foot Pounds
- Q:Hello, i have a 1987 volkswagen cabriolet that i purchased earlier this year. So far its been a pain in the butt. Recently i noticed it overheats real quick, but it didnt use to. then i noticed the coolant/antifreeze was being used up like no other! I discovered, after being parked at work, that it was leaking.it leaks basically anything i put in there now!! it leaks from the water pump housing,.,.... at least thats what the internet said it was.. its leaking from the end of the hose that connects to the engine... (the hose that comes from the coolant reservoir.)What do i do? I dont feel any cracks? does this part crack? is it an o-ring or somehting? I am really absolutely NOTHING ABOUT CARS. Please help!!
- HI It is an o-ring Loss the 4 bolts holding the pump and put some silicon glue on the o-ring and get it back.
- Q:Water pump motor often caused by water can not run, how can solve?
- You are immersed in water or oil pump pump, if flooding do not be afraid, if you put oil thread wrapped with waterproof tape, general water pump inlet is in the end, you want what the price of copper or aluminum pumps, the price is basically the same, do not buy too cheap water pump
- Q:I'm using an old Mitsubishi Lancer. Recently I changed my water pump it was leaking.To me it looked like a piece of metal, with a small fan thing (not motorized) How can it fail? There is no mechanics to it, just like a pipe with a fan (or turbine)I also messed with my radiator, I unhooked the main hose to clean out the coolant, since the plug was jammed. Could this have contributed to the failing of my water pump?
- if the plug was jammed then the most likely cause was some type of sealant someone put in the radiator to fix a leak......this is a prime example of why I say never to use the sealers in your engine....... what happened to your water pump is really rather simple......the waterpump (WP) is a simple device that spins and has bearings......the coolant you buy in the store has lubricants in it to keep the waterpump luricated.....the sealer that was put into the cooling system sealed of the passages the coolant uses to lubricate the WP bearings......this created too much friction and wore your bearing out causing the pump to fail!!!!!!......you need to flush the cooling system thoroughly several times to get all the sealer out......even then it will take a little luck and lots of praying for the sealer not to plug your engine water jacket and cause overheating!!! good luck!!!
- Q:There is a 5.5KW before the pump head is now 25 meters and flow of 20 cubic meters, but not up to the requirements, I think this is like with a motor pump, lift more than 20 meters, the flow is about 40 cubic meters of water pump, please inform the models and parameters, thank you
- With the motor pump are pump according to the actual need of work with you in the head, under the same water doubled, the motor is certainly not enough, you should this motor pump change together in order to meet the requirements of.
- Q:What is the reason that the water supply of pump is getting smaller?
- What kind of pump is it, home pump or factory pump? Single stage impeller or multistage impeller? Vertical or horizontal? Is it single suction or double suction? Different structure of the day pump has different causes of failure. But in general, there are several aspects: 1., the water inlet is small, the inlet pipe is blocked; 2., the blade is worn or broken; 3., the motor speed drops; 4., sealing serious leakage; 5., cavitation phenomenon.
